Strange lights in the sky over Spring Hill. Triangular in shape no sound

I was driving my truck to the southern portion of my ranch to check for any open gates when I saw a faint light thru the trees. As I approached a clearing I could see a faint outline with about 6 small lights underneath. It hovered for about 3 minutes and then slowly headed north and out of sight. I am a former Air Force avionics tesc and have seen some of the strangest looking flight formations but this thing didn't make any noise whatsoever
